Abstract: VALVE      This application is a division of my copending Canadian application Serial No. 369,588, filed April 1, 1981.          Abstract of the Disclosure A valve and particularly a safety valve for use in controlling flow from a well in which an external motor is utilized to shift the actuator of a valve such as a ball valve.  The reciprocating rod of the motor is protected by resilient means between the crosshead attached to the motor and the reciprocating actuator.  The actuator is latched when the valve is in the open position so that it cannot be moved to closed position except by movement of the reciprocating motor.  The valve and seat assembly are designed to be re-placed as a unit and can be fabricated as a subassembly with the valve in exact open alignment when the reciprocating actuator is in full valve open position as determined by a stop against which the valve member bottoms.    The valve may have its actuator moved beyond the normal reciprocating range for opening and closing of the valve member to permanently lock the valve member in full open position without hindering further reciprocation of the actuator so that it can be used as a control for a secondary valve.  The housing and actuator are provided with latch means and a secondary valve with a secondary actuator are landed in the housing and in the actuator so that reciprocation of the actuator then moves the secondary valve between open and closed positions.

Abstract: AN ANALYTICAL INSTRUMENT          THERMOELECTRIC TEMPERATURE REGULATOR                          Abstract A temperature control system used to precisely and accurately control the temperature of a fluid stream in an analytical system designed for investigation of the chemical constituents of the fluid stream.  One example of use is in chromatography such as for the chromatographic column in an amino acid analyzer system.          The temperature control system utilizes a set of thermo-electric modules to transfer heat between a thermocon-ductive block which holds the chromatographic column and an air exchange heat sink which obtains heat from or disposes heat into ambient air as required.  The control system regulates the temperature at a very rapid rate in order to minimize the recycle time of the instrument.

Abstract: ABSTRACT                A system and apparatus for the controlled intermixing of hydrogen gas with oxygen and other  non-combustible gases in a combustion system is disclosed and can be used, for example, in an internal combustion engine.  In the system, there is provided a hydrogen/oxygen generator, a water reservoir including a gas collection chamber, non-oxidizing plates in the reservoir and a direct current source connected to the plates for disassociation of hydrogen and oxygen atoms.  The hydrogen gas is directed to a mixing chamber employing a fuel linear control valve.  Non-combustible gas is also introduced into the mixing chamber and there is also ambient air intake means for combining air with the hydrogen gas and non-combustible gases.   Controlled amounts of hydrogen gas combined with the non-combustible gas and ambient air are fed to the combustion chamber of the internal combustion engine.

Abstract: ABSTRACT OF THE DISCLOSURE       A process and apparatus for the vulcanization of the insulation of an electric cable in which the cable core with the insulation thereon are passed through a tube filled with a liquid having a specific weight substantially equal to the specific weight of the insulation.  The section of the tube nearer the entrance end is supplied with degassed liquid at vulcanizing temperature and the following section is supplied with degassed liquid at a temperature for cooling the insula-tion, and because the liquid has different viscosities at the two temperatures, a liquid interface is produced between the two portions which interface is maintained during the vul-canizing of the insulation.  During the vulcanizing of the insulation, a portion of the liquid in at least one section is removed and treated to remove vulcanization products.

Abstract: ABSTRACT         A snap-on unitary, one piece photo-optical item position sensor fabricated as a clothes-pin-like plastic member from a material which is substantially transparent to infra-red radiation obviating lenses.          The sensor member is bifurcated at one end to form two parallel leg portions the outboard end of each one of which carries one element of the photo-optical sensing apparatus. The opposite end of the sensor member is rectangularly shaped and slotted on opposite parallel sides forming a polarized receptacle for a mating polarized plug as well as a handle for griping.  Compression of the handle portion contacts the slotted end slightly while opening or spreading the two parallel leg portions enabling the sensor to be snapped over an orthogonally disposed item guide or track.  Oppositely disposed parallel members on the lower portion of the track automatically position the sensor over the track.  A notch in the lower track permits the optical sensing apparatus to be axially aligned perpendicular to the item guide/track.

The power-up mode switch allows user selection of the particular mode in which operation resumes upon power restoration, but the user power up mode selections do not include all the operational modes selectable by the momentarily-actuated user mode selection switches.  Thus operation continues in a mode at least appropriate for the season.

Abstract: ABSTRACT OF THE DISCLOSURE This pressure sender or transducer comprises a metal housing having a steel cover and containing a rolling diaphragm which is secured over a cavity in the housing to communicate at one side with fluid under pressure,  such as the oil in the crankcase of an auto-mobile.  Mounted centrally in the opposite side of the diaphragm is a rigid cup, which rotatably supports one end of a reciprocable plunger which in one embodiment carries two sets of equi-angularly spaced, resilient metal wipers or contacts, four of which are slidably engaged with the cylindrical operating surface of a printed resistor, which is mounted in the closed end of the cover, and four others of which are slidably engaged with the inner peripheral surface of the cover itself. The resistor comprises a steel can having a thin layer of porcelain baked on its outer peripheral surface, and a thin, cylindrical layer of resistance material printed and baked onto the porcelain layer with one end in electrical contact with the steel can.  A coiled compression spring resists movement of the plunger in one direction, but cannot apply any rotational torque to the diaphragm because the plunger is mounted for rotation relative to the diaphragm.  In a second embodiment the resistor and a ground conductor are printed on the plane surface of a ceramic substrate, and are engaged slidably by two sets of fine wires carried by the plunger.

Abstract: ABSTRACT OF THE DISCLOSURE          Tape is wound into a package by traversing the winding position along a cylindrical core such that the winding position is intermittently and repeatedly halted at a plurality of positions arranged axially of the core so that at each position the tape is wound spirally following which the winding position is traversed to the next adjacent position.  The spirals comprise at least one turn and more of the winding time is spent in forming spirals than in traversing between spirals. The spacing between the positions is such that the spirals do not overlap and such that the gap between the spirals is less than the width of the tape.  The number of spirals wound at each position is insufficient to cause a step which interferes with traverse back to the position. Control of the traverse movement can be achieved either electronically by a pulse counter connected to the package support shaft or electro-magnetically by a control drum driven from the package support shaft.

Abstract: ABSTRACT OF THE DISCLOSURE         One corner connecting element (5), in the form of a rail, is present at each corner of a box-like structure having four side walls (3) and one bottom or rear wall (2).  With longitudinal grooves I the rail engages bent-over edge portions (13) of the walls of the structure.  The corner connecting elements So) are preferably realized in two parts (6, 7) in the longitudinal direction, the parts being held together by screws (12).  Since the outside of the connecting rail (5) is embodied in the shape of one quarter of a circle, the corners of the structure are rounded.  The fabrication of such structures, such as bathroom cabinets and the like, is simplified as a result, because welded connections can be dispensed with.
